m - (x -n)^2 = ? HELP MEEEE
Hi guys,
Im new here and wasn't sure what section to post this in :)
Doing as maths at the moment.
m - (x - n)^2 =m - x^2 - N^2 I thought...
But its
m - (x - n)^2 = n^2 + 2nx - x^2
Could someone explain why 2nx appears (It must be a basic rule that i have forgotten since doing gcse maths)
If you could help that would be much apreciated :)
